Quiz 9 Flashcards
Lin is a type 1 diabetic who forgot to bring her insulin today. By the end of the day, Lin is not feeling well. Which would NOT be a characteristic of Lin at the end of the day with no insulin injections?
Decreased thirst.
Which hormone would promote the storage of triglycerides?
insulin
Amino acids from the diet not used for synthesizing proteins can be used in ____________.
gluconeogenesis
Untreated Type 1 Diabetes mellitus is characterized by ___________.
loss of body fluid due to increased urine output
In untreated type 1 diabetes mellitus (insulin-dependent diabetes mellitus), acidosis occurs because ____________.
excessive lipolysis results in increased plasma fatty acid levels, which the liver converts to acidic ketones
If an individual consumes excess calories in the form of carbohydrates, the excess energy is stored as ________.
adipose tissue
On a tour of African countries, Dom contracts a bad case of traveler’s diarrhea. Because he cannot eat very much, his body starts to use energy sources other than carbohydrates. This would result in
all of the choices are correct
The principal means of increasing heat production in response to a cold environment is
shivering thermogenesis and increased voluntary activity.
Which correctly describes an action of insulin?
It increases the uptake and utlization of glucose by skeletal muscle and adipose cells.
Uncontrolled type I diabetes mellitus has the potential to ________.
induce metabolic acidosis
Formation of glucose from noncarbohydrate molecules is called ________.
gluconeogenesis
The Atkins and South Beach diets are considered ketogenic because ____________.
they cause the body to burn calories from noncarbohydrate sources
A patient has a mutation that does not allow hormones to stimulate the activity of enzymes in the fed state. Based on push-pull control, what would you expect to observe?
More glucose and less glycogen as insulin cannot activate enzymes.
Which of the following demonstrates a situation when the metabolic rate in A is greater than in B?
A single person in two different thermic states; A = exercise induced hyperthermia, B = surgically induced hypothermia
The liver and skeletal muscles store glucose as ________ for a ready energy source.
glycogen
Which of the following best explains why rings on your fingers typically fit tighter in the summer than in winter?
The body is trying to maintain normal body temperature by increasing heat loss. One way to do that is for the cutaneous blood vessels to dilate. This dilation results in the swelling of the fingers.
Drugs that activate PPAR gamma receptors are useful in the treatment of what metabolic disorder?
Type 2 Diabetes
Dehydration can result from __________.
both heat exhaustion and diabetes
Metabolism is a term that describes
all chemical reactions that take place within an organism.
During exercise, skeletal muscle cells can upregulate alternative glucose transporters which are independent of insulin signaling, therefore exercise is useful for individuals with type 2 diabetes.
True
